Hi everyone,
we have a 5800m2 property in the south west of France with a slope ranging from 25 to 30% in the field where we would like to establish an orchard or some sort of food forest along the countour lines. We thought swales would be good but I have recently read that they are not appropriate when slope is greater than 15%.
The property is situated in Bardos, 64520 France. Rainfall can be dramatic :
https://www.infoclimat.fr/climatologie/normales-records/1981-2010/labastide-clair/valeurs/64289001.html
Average annual rainfall = 1400mm
Max rainfall in one day 100mm
A the moment it is a pasture with 3 small sheep grazing. There is a small woodland on the west side where the main winds come from.
The soil is heavy clay, very sticky when wet, so hard when dry.
UPDATE : I have read that Bill Mollison calls a 50% slope what engineers would call a 100% slope (source :
). My understanding is that our 25% slope represents a fall of 25m vertically for 100m horizontally so the ingeneer version.

Any thoughts / advice for us to grow fruits there regarding earthworks ? Thank you for your time, very much appreciated !
